AS5163
12-Bit Automotive Angle Position
Sensor
General Description
Figure 1:
Added Value of Using AS5163
The AS5163 is a contactless magnetic angle position sensor for
accurate angular measurement over a full turn of 360º. A sub
range can be programmed to achieve the best resolution for
the application. It is a system-on-chip, combining integrated
Hall elements, analog front-end, digital signal processing and
best in class automotive protection features in a single device.
To measure the angle, only a simple two-pole magnet, rotating
over the center of the chip, is required. The magnet may be
placed above or below the IC.
The absolute angle measurement provides instant indication of
the magnet’s angular position with a resolution of
0.022º = 16384 positions per revolution. According to this
resolution the adjustment of the application specific
mechanical positions are possible. The angular output data is
available over a 12-bit PWM signal or 12-bit ratiometric analog
output.
The AS5163 operates at a supply voltage of 5V and the supply
and output pins are protected against overvoltage up to +27V.
In addition, the supply pins are protected against reverse
polarity up to -18V.
Ordering Information and Content Guide appear at end of
datasheet.
